Not just red in tooth and claw: biology's big debates

In the second of a series, biologist and priest, Andrew Davison, examines why it’s important to keep up with biology’s big debates.

Andrew works at the intersection of theology, science and philosophy. He is Canon and Regius Professor of Divinity at Christ Church, Oxford.

There’s hardly been a livelier time for evolutionary science than today; indeed, passions can run high. It’s not that Darwin’s vision of evolution is fundamentally in doubt: species adapt by natural selection, there’s variation between individuals, and those better adapted for their environment survive more often, passing on their genes to their children. In that, the theory of evolution stands, but many other parts of the evolutionary picture from the second half of the twentieth century are coming under criticism. That includes the following maxims:  

‘the only significant form of inheritance involves genetic code’, 

‘nothing that happens to an organism during its lifetime is passed on to its progeny’,  

‘we agree what we mean by “species”’,  

‘genes pass down the branches of the tree of life, not between them’,  

and ‘evolution is fundamentally all about competition, not cooperation’. 

Among the excellent crop of writers on these themes, Eva Jablonka and Marion Lamb stand out for their elegant prose, and a gift for communicating complex ideas clearly. As they recognise, the standard mid-twentieth century model of evolution might be worth criticising, but it’s also landed all sorts of important basic points. (They list ten.) The shortfall of the earlier, dominant theory was in being too narrow, with each insight too quickly eclipsing others.  

Here are two examples. First, the classic twentieth century picture saw inheritance in terms of DNA and genes, passed on by ‘germline’ cells, such sperm and pollen. That’s all true, but it shouldn’t restrict our wider view of inheritance to that. Today, writers such as Jablonka and Lamb stress that organisms inherit from their parents (or parent) in all sorts of ways.  

A second plank of the twentieth century picture is that evolution involves descent from a common ancestor. Again, that says something vital, even central, accepted by evolutionist old and new. The twentieth century position, however, added a restriction: that’s all that’s important on this score. The newer perspective recognises that while genes are – of course – central, and passed on from parent to child, organisms also swap genes between themselves (between branches of the tree of life, not just along those branches), even between very different species. 

If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

There’s a lot of excitement around these sorts of claims (and, remember, Jablonka and Lamb make eight more), and that can get quite noisy. Defenders of the older, narrower picture typically say that the newer themes are simply fuss over minor points. Advocates of the newer perspective disagree, saying that the twentieth century picture risks missing some important features of biology, which are now coming into better focus. 

Why such debates matters 

Why might this ferment among biologists matter for a site like this one, and for theologians, and discussions of religious matters? Well, for one thing, as I pointed out in my previous article, nothing quite dissolves the supposed animosity between science and religion (which is, after all, a relatively recent invention) like theologians and religious people getting excited about biology. It’s also important that any humanities scholar, the theologian among them, who’s engaging with science should keep up to date. If we’re not careful, what’s written and taught (not least by theologians), even with the best will in the world, will be thirty or even fifty years out of date. 

But there’s more at stake. As we have seen, the twentieth century picture, for all it brought an admirable clarity to evolutionary thought, was reductionistic. We see that in Jablonka and Lamb’s exhortation to scientists: ‘yes, stress x, but don’t think that means you have to deny y.’ A religious vision tends to be an expansive one. It wants to recognise the reality and value of all sorts of things. Yes, there’s matter, atoms, molecules, and genes, but there’s also organisms, agents, cultures, groups, economies, hopes, loves. They’re all real. We can’t reduce one to the other: not organisms to genes, or agents to economies. A turn from reduction is welcome. 

More than that, almost everything in the emerging twenty-first century view of evolution is fascinating from a theological perspective.  

Take convergence, for instance. It turns out that evolution isn’t just driven by randomness, or by the demands of the surroundings. Also important are various features of physics, or mathematics – the contours of reality – that throw up elegant solutions to evolutionary problems, which are adopted by evolution time and again. Wherever you need to sturdy and space-efficient packing of cells (as in a honey comb, or a a wasp’s nest), the hexagon is ready and waiting.  Wherever there’s water or air to navigate, the laws of fluid dynamics are bound to throw up wings, and bodies shaped like fish, dolphins, and penguins (which are all quite similar in shape).  

How do we know this? Because evolution has converged on wings and that body shape independently, many times, as also on eyes, and everything else that Simon Conway Morris lists in the nine closely printed columns of convergences in the index to his book Life’s Solution. Evolution certainly involves randomness and need, but alongside them is something more like Plato’s forms: timeless realities, there to be discovered and put to work. Among the more theological of these eternal verities, covered in Conway Morris’s book, are perception, intelligence, community, communication, cooperation, altruism, farming, or construction 

 Exceeding a zero-sum game 

Then there’s cooperation. Ever since Darwin’s Origin was published, and, even more, ever since Tennyson wrote about nature ‘red in tooth and claw’, theologians have been embarrassed about the place of cooperation in their vision of the world. Now, however, it turns out, competition isn’t the only force at work in biology or evolution after all. One of the features of reality that evolution discovers and puts to work again and again is cooperation, and ways to exceed a ‘zero-sum’ game. We see that in cooperation within a species, but also in cooperation between species, which is ubiquitous in nature: called mutualism, it’s found everywhere. As a rule, once two species stick around in proximity for the long run, down many generations, their relationship will turn to mutual benefit.  

Ethicists are often wary of the suggestion that we can look at the way things are, and read a moral code there (getting an ‘ought’ from an ‘is’), but it’s an unusual person whose vision of right and wrong isn’t shaped, to some degree, by a sense of what the world is like. Well, it turns out that nature bears witness to the enduring worth of cooperation, and not only to competition.   

In the first of these articles on biology, I pointed out the significance of ethics in thinking about biology, and about evolution in particular. For better or worse, and often for worse, thinking about evolution has been an ethical, social, political story. The evolutionary has been put to work for immoral, ends. It turns out to be wrong twice over to suppose evolution commends only competition. It’s wrong, first of all, because we are rational creatures, who can aspire to an understanding of good and evil that transcends the realm of nature. But also, as we now see, it’s wrong even to suppose the nature is only red in tooth and claw. There’s competition, but there’s also a lot of cooperation.

The myth of secular neutrality

Where academia went wrong.

In the recent horror-thriller Heretic, Hugh Grant plays Mr. Reed, a sharp-witted psychopath who imprisons two missionaries, subjecting them to ceaseless diatribes about the supposed irrationality of all religions.  Mr. Reed is also a terribly smug, self-righteous bore, a caricature of the fervent atheist who dismisses faith as mere superstition while assuming atheism is objective and neutral.  

This kind of assumption lies behind the criticisms directed by secularists at those who argue from a position of faith, as we saw recently with the debates on the Assisted Dying Bill. Yet, the notion of secular objectivity is itself a fallacy. Secularism, like any worldview, is a perspective, ironically one that is deeply indebted to Christianity, and humanity’s history of abandoning faith and its moral foundation has had disastrous consequences.  

Secularism is a bias, often grounded in an ethical vanity, whose supposedly universal principles have very Christian roots. Concepts like personal autonomy stem from a tradition that views life as sacred, based on the belief that humans are uniquely created in God's image. Appeals to compassion reflect Jesus’ teachings and Christian arguments for social justice throughout history. Claims that the Assisted Dying Bill was "progressive" rely on the Judaeo-Christian understanding of time as linear rather than cyclical. Even the separation of the secular and sacred is derived from Jesus’ teaching to “render to Caesar what is Caesar’s and to God what is God’s”. Authors like Tom Holland in Dominion and Glen Scrivener in The Air We Breathe have shown how Western societies, though often disconnected from their Christian roots, still operate within frameworks shaped by centuries of Christianity.

The antidote to human pride and self-deception was to be found in the Almighty.  Ironically, it was this humility, rooted in a very theological concern about human cognitive fallibility, that gave birth to the scientific method. 

A political secularism began to emerge after the seventeenth century European religious wars but the supposed historical conflict between science and religion, in which the former triumphs over superstition and a hostile Church, is myth. Promoted in the eighteenth century by figures like John Draper and Andrew White, this ‘conflict thesis’ persists even though it has been comprehensively debunked by works such as David Hutchings and James C. Ungureanu’s Of Popes and Unicorns and Nicholas Spencer’s Magisteria. Historians now emphasize the complex, often collaborative relationship between faith and science. 

Far from opposing intellectual inquiry, faith was its foundation. Medieval Christian Europe birthed the great universities; this was not simply because the Church had power and wealth but because knowledge of God was viewed as the basis for all understanding. University mottos reflect this view: Oxford’s "Dominus illuminatio mea" (The Lord is my light), Yale’s "Lux et Veritas" (Light and Truth), and Harvard’s original "Veritas Christo et Ecclesiae" (Truth for Christ and the Church). This intertwining of faith and academia fuelled the Enlightenment, when scientists like Boyle, Newton, and Kepler approached the study of creation (what Calvin described as ‘the theatre of God’s glory”) as an affirmation of the divine order of a God who delighted in His creatures “thinking His thoughts after Him”.   

Their Christian beliefs not only provided an impetus for rigorous exploration but also instilled in them a humility about human intellect. Unlike modernity's view of the mind as a detached, all-seeing eye, they believed man’s cognitive faculties had been diminished, both morally and intellectually, by Adam’s fall, which made perfect knowledge unattainable. Blaise Pascal captures this struggle with uncertainty in his Pensées.  

“We desire truth, and find within ourselves only uncertainty....This desire is left to us, partly to punish us, partly to make us perceive from whence we have fallen.”  

For Pascal and his believing contemporaries, the antidote to human pride and self-deception was to be found in the Almighty.  Ironically, it was this humility, rooted in a very theological concern about human cognitive fallibility, that gave birth to the scientific method, the process of systematic experimentation based on empirical evidence, and which later became central to Enlightenment thinking. 

Orwell was not alone in thinking that some ideas were so foolish that only intellectuals believed them. 

Although many of its leading lights were believers, the Enlightenment era hastened a shift away from God and towards man as the centre of understanding and ethics. Philosophers like David Hume marginalized or eliminated God altogether, paving the way for His later dismissal as a phantom of human projection (Freud) or as a tool of exploitation and oppression (Marx), while Rousseau popularised the appealing idea that rather than being inherently flawed, man was naturally good, only his environment made him do bad things.  

But it took the nihilist Nietzsche, the son of a Lutheran pastor, to predict the moral vacuum created by the death of God and its profound consequences. Ethical boundaries became unstable, allowing new ideologies to justify anything in pursuit of their utopian ends. Nietzsche’s prophesies about the rise of totalitarianism and competing ideologies that were to characterise the twentieth century were chillingly accurate. Germany universities provided the intellectual justification for Nazi atrocities against the Jews while the Marxist inspired revolutions and policies of the Soviet and Chinese Communist regimes led to appalling suffering and the deaths of between 80 and 100 million people. Devoid of divine accountability, these pseudo, human-centred religions amplified human malevolence and man’s destructive impulses.      

By the early 1990s, the Soviet Union had collapsed, leading Francis Fukuyama to opine from his ivory tower that secular liberal democracy was the natural end point in humanity's socio-political evolution and that history had ‘ended’. But his optimism was short lived. The events of 9/11 and the resurgence of a potent Islamism gave the lie that everyone wanted a western style secular liberal democracy, while back in the west a repackaged version of the old Marxist oppressor narrative began to appear on campuses, its deceitful utopian Siren song that man could be the author of his own salvation bewitching the academy. This time it came in the guise of divisive identity-based ideologies overlayed with post-modern power narratives that seemed to defy reality and confirm Chesterton’s view that when man ceased to believe in God he was capable of believing in anything.  

As universities promoted ideology over evidence and conformity over intellectual freedom, George Orwell’s critique of intellectual credulity and the dark fanaticism it often fosters, epitomized in 1984 where reality itself is manipulated through dogma, seemed more relevant than ever.  Orwell was not alone in thinking that some ideas were so foolish that only intellectuals believed them. Other commentators like Thomas Sowell are equally sceptical, critiquing the tenured academics whose lives are insulated from the suffering of those who have to live under their pet ideologies, and who prefer theories and sophistry to workable solutions. Intellect, he notes, is not the same thing as wisdom. More recently, American writer David Brooks, writing in The Atlantic, questions the point of having elite educational systems that overemphasize cognitive ability at the expense of other qualities, suggesting they tend to produce a narrow-minded ruling class who are blind to their own biases and false beliefs. 

It was intellectual over-confidence that led many institutions to abandon their faith-based origins. Harvard shortened its motto from "Veritas Christo et Ecclesiae" to plain "Veritas” and introduced a tellingly symbolic change to its shield. The original shield depicted three books: two open, symbolizing the Old and New Testaments, and one closed, representing a knowledge that required divine revelation. The modern shield shows all three books open, reflecting a human centred worldview that was done with God. 

However, secular confidence seems to be waning. Since the peak of New Atheism in the mid-2000s, there has been a growing dissatisfaction with worldviews limited to reason and materialism. Artists like Nick Cave have critiqued secularism’s inability to address concepts like forgiveness and mercy, while figures like Ayaan Hirsi Ali and Russell Brand have publicly embraced Christianity. The longing for the transcendent and a world that is ‘re-enchanted’ seems to be widespread.  

Despite the Church’s struggles, the teaching and person of Christ, the One who claimed not to point towards the truth but to be the Truth, the original Veritas the puritan founders of Harvard had in mind, remains as compelling as ever.  The story of fall, forgiveness, cosmic belonging and His transforming love is the narrative that most closely maps to our deepest human longings and lived experience, whilst simultaneously offering us the hope of redemption and - with divine help – becoming better versions of ourselves, the kind of people that secularism thinks we already are.
